UNITED STATES PATENT OFFICE.

JAMES E. IV ATKINS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE- IIALF TO JOIIN IVILSON, OF SAME PLACE.

WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 462,521, dated November 3, 1891.

Application filed January 14, 1891. Serial No. 377,754. (No model.)

To aZZ whom it may concern.-

Be it known that I, JAMES E. IVATKINS, a citizen of the United States, residing in the city and county of- Philadelphia, State of Pennsylvania, haveinvented a new and useful Im pro veinentin Washing-Machines,which iinproveinent is fully set forth in the following specification and accompanying drawings.

IO My invention consists of a novel mannerof securing the beater or rubber and a strengthening-spider of a washing-machine, as will be hereinafter more fully set forth.

Figures 1 and 2 represent perspective views I5 of a portion of a Washing-machine embodying my invention. Fig. 3 represents a vertical section thereof,

Siinilar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates a rubber or beater of a washing-machine, the same consisting of a head with rubbers l3 thereon, said parts being preferably formed of wood.

C designates a spider formed of metal, whose upper face is formed with studs or pins D, which enter openings E in the head A, said spider being connected with a rotatable shaft F, the latter passing through the head. Projecting from the shaft F, just above the head A, are lugs G, it being noticed that the portion of the shaft below said lugs is of conical form to accord with that of the opening in the head A.

H designates a key consisting of a plate having an oblong opening, said key being fitted on the shaft F and adapted to pass over the lugs G, but when rotated to interlock with said lugs and thus prevent separation of the spider and head.

shape of the opening of the key it is to be understood that the length is greater than the width.

In referring to the oblong The operation is as follows: The spider is applied to the head and the studs D fitted 5 into the openings E. The lugs G now being above said head, the key is lowered and readily passes the lugs, owing to the long direction of the opening of the same registering with said lugs. The key is then turned, whereby the long direction of the opening is at a right angle with the lugs, and said key is then interlocked with the lugs within the same, thus connecting the spider and head and preventing separation of the same until the key is again properly turned, so as to be raised clear of the lugs.

The lower end of the shaft F is provided with a head K for connecting the shaft with the bottom of the tub, similar to that shown in the application for Letters Patent, Serial No. 356,666, filed on or about the 25th dayof June, 1890.

Having thus described n1yiuvention,w'l1at I claim as new, and desire to secure by Letters 6 5 Patent, is

1. In a washing-machine, a shaft rigidly connected to a spider or plate, rubber resting on said spider and having the said shaft passing through its center, logs on said shaft i above the rubber, and a slotted key-plate removably fitted between said lugs and the rubber, said parts being combined substantially as described.

2. A spider or plate C, having studs D, and

a head A, having openings E to receive said studs and a central opening for an operatingshaft, in combination with a key H, which is fitted to said shaft and engages with lugs on said shaft above said head, substantially as described.
